Application filed .Tune 8,

lhis invention relates to improvements in power lift plows and more particularly to means 'for controlling the operation o't the clutch devices whereby the liitinp,- connec-v tions are coupled to a carrying wheel of a plow-one object oi my present invention being to provide improved means for permitting the manual operation of the control member o'j a power lift mechanism when such mechanism is associated with a crank axle of a wheeled plow, and to `eilectually overcome the objections and annoyances incident to the use of a cord such as commonly employed for operating thev control lever Ot lifting mechanism, such cord being lia-ble to be blown about by the wind and to become caught in lugs ot the tractor wheels, thus rendering it difficult for the opera-ter to quickly grasp and operate it; K

lilith this and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set 'forth' and pointed out in they claim. j

The accompanying drawing is a view in Iide elevation of a wheeled power litt plow structure showing an embodiment of my invention.

The frame of the plow structure comprises a plurality of beams 1 suitably spaced and braced and having standard portions with which plow bases v2 are connected. Suitable bearings are provided for the accommodation of crank axles 3 and 4 and these axles are adapted for connection, with carrying wheels,-such as aA land wheel 5 and al furrow wheel 6.

Power lift mechanism application ,granted to Herman E. Altgelt ifiugust 5, 1924 and designated by No.'1,503,

779. This mechanism includes an arm 9 secured to one ot the crank axles and screw adjusting means 10 connected with said amm-said screw adjusting means including,`

j 7 is associated with the land wheel crank axle and land wheel 1923. Serial No. 644,177.

a manually operable shaft 11 mounted to turn in a sleeve or knuckle 12 supported by a standard 13 secured to the plow frame..

The control lever 14 of the power lift mechanism is pivotally-supported by a part secured to the axle as disclosed in Patent No. 1,496,441above mentioned, and has connected with its upper end portion, a rod 15. This rodpasses forwardly and freely through an eye or guide 1G supported upon and by the sleeve or knuckle 12. The i'or- .wardly ,projecting portion of the rod 15 is' provided with a loop or hand hold 17 which will be disposed within convenient reachof the operator riding upon a tractor with which the plow structure is. connected.

ll/'ith the use of my improvement, a rigid, manually operable member is loosely connected ,at its rear end with the control lever olf the power lift mechanism and is prevented from lateral displacement by the loop or guide 16. The handle end of the rod is always in position to be graspedv by the operator and the inconveniences and annoyances incident to the use of a cord or rope .heretofore commonly employed for operating thecontrol lever of the lift mechanism will be eil'ectually obviated. 1

Having' fully described my invention what l claim as new and desire to secureby Letters-Patent, is:

ln a power liftplow, the combination of crank axles, ground wheels on the axles, va plow i'rame carrying;1 earth-working means and provided. with bearings for the axles,

power lift means associated with one of the wheels and connected to theframe 'for raising the latter, a control lever cooperable directly with said power litt means and supported independently of said 'frame whereby vthe latter will bei capable of vertical movement independently of said control lever, an operating rod connected with said control lever and extending` forwardly above the frame, a guide for said rod, and means-on the 'frame adjacent the front end thereof' Jfor supporting said guide whereby theV operatingV rod will be maintained in position to be manipulated from a position in iront of the plow. 1

In testimony whereof,
